Oriental rugs are essentially made with knotted pile, a textile that is formed with upright loops of yarn. There are two common types of knots in Brooklyn/Manhattan, most used to make Oriental rugs.
Persian knots are called Senneh, and Turkish knots are called Ghiordes. Both type are tied around pairs of warped strings. Senneh knots are asymmetric. The fabric is opened on one side. It does not matter if it us right or left. This knot is the most widely used. Ghiordes knots, on the other hand, are indeed symmetric. Both sides open up in the center. These knots are found to be used in Oriental rugs made in Turkey, Armenia, Azerbaijan and Iran.
There are also jufti knots. These are also known as false knots and can be done in either a Persian or Turkish style. These make for an inferior quality of rugs, because they use half the material and take half the time to make. Unfortunately they also only last half as long. Some Oriental rug types, like the Bokharas, will disperse jufti knots with more traditional Persian knots.
Unlike most rugs, Oriental rug quality does not just depend solely on thread-count. It is also dependent on knot density. This is the amount of knots that are used per square inch. So the quality of an Oriental rug is directly proportional to the rug’s knot quantity.
Different areas of the East use different forms of measurement, but one thing is the same. Oriental rugs are graded on the amount of knots that are used. Many cultures use a two number system, except for China which uses one number to state how many knots are in each line of thread.
